Kanlaon Volcano had two ash emission events on Thursday morning, Oct. 23, sending grayish plumes rising up to 600 meters above the summit crater, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
Time-lapse footage from the IP Camera at the Kanlaon Volcano Observatory in Canlaon City captured the first emission from 5:30 a.m. to 7:29 a.m. and the second from 7:39 a.m. to 8:05 a.m.
Both plumes drifted west-southwest due to prevailing winds.
Phivolcs continues to maintain Alert Level 2, indicating moderate-level unrest.
Residents and visitors are reminded to avoid the four-kilometer permanent danger zone around the crater due to the risk of sudden explosive events, pyroclastic density currents, rockfalls, and harmful volcanic gases.
Local government units are urged to maintain preparedness for possible evacuations, while civil aviation authorities are advised to avoid flying near the volcano's summit because of potential ash emissions that could affect aircraft safety.
Phivolcs also warned of possible lahars and sediment-laden streamflows in rivers and drainages around the volcano should heavy rainfall occur.
